Carbon capture

ExxonMobil just signed a lease for 271,068 acres of undersea land off the coast of Galveston, Texas to capture and permanently inject carbon emissions into the underwater rock bed, making it what will be the largest CO2 dump in the United States.

A technique originally developed to combat acid rain has the potential to pull an enormous amount of carbon dioxide out of the atmosphere – while helping to deacidify oceans, restore rivers and boost biodiversity and fish populations.

Tulip trees have been around for millions of years, but a new analysis of their structure has revealed a previously unknown type of wood. The finding could explain why the trees are great at sequestering carbon and help our efforts to do the same.

A new material tackles the carbon problem of concrete production and usage by employing a pretty unusual workforce: cyanobacteria. The bio-cement these micro-organisms help to produce harnesses a process that's existed in nature for 3.5 billion years.

The production of concrete is a major contributor to worldwide CO2 emissions, however Nendo showcases a greener alternative with its Block-Wall House, which was part-built using a novel concrete that actually captures carbon-dioxide.

The world’s largest ocean-based carbon dioxide removal plant is being built in Singapore, and will be capable of capturing 8 million lb of CO2 per year while also producing 231,000 lb of carbon-negative hydrogen.

A remarkable pilot project installed on a 240-m (787-ft) container ship has proven it's possible to capture at least 78% of emissions from the smokestacks of cargo ships and convert the CO2 into limestone pebbles, which can be offloaded and sold.

In an effort to mitigate human-caused climate warming, scientists are focused on ways to remove carbon dioxide from the atmosphere. One of the more novel ways to do this has just been announced by scientists employing a smart dual-method process.

With complex ecological modeling, scientists have found that plants may be soaking up 20% more CO2 than earlier predicted. It's no "get-out-of-jail-free card," but it highlights the crucial role nature needs to play as we try to stem global warming.

Researchers have created a paint containing living cyanobacteria that produces oxygen and can capture carbon dioxide. The bacteria’s ability to withstand extreme environments means the paint could even be used in outer space.

CO2 emissions and plastic waste are two major environmental problems, but a Cambridge device may help tackle both at once. The team demonstrated a new version of their solar reactor, which uses sunlight to convert CO2 and plastic into useful chemicals.

Captura Corporation has developed a revolutionary plan to remove carbon emissions by creating an aquatic purification facility in the middle of the sea. The company intends to extract carbon dioxide from ocean water using only renewable electricity.
